Hi everyone!

I just bought my first chevy a week ago, but i would need some help...

The car was imported to Sweden in -87, and was then modified according to Swedish laws. New yellow turn signals
was added to the rear, on the sides and in the front.
But i want to change it all back to stock, remove the yellow turn signals and have them connected to the taillights instead, as
it is supposed to be.
The thing is, all the cables have been changed and messed with, and there´s a ton of extra cables added under the steering wheel/hood
because of an aftermarket alarm system protection thingy.

Does anyone have the schematics over the light system?

You can use '77 to '88 when searchin parts or manuals.

Chevy didnt change many things mostly body lines.

First welcome to the Vanning web site and congrats on owning your first Chevy G series van.
It would probably be best to post any questions about the Chevy van in the Chevy section.
First thing you should do is order a copy of the shop manual for your year of van and hopefully you can find a copy of the electrical manual (if one is available). Has electrical schematics of each section and systems of the van. Much easier to work with then the electrical section in the shop manual.
Not sure how the “changes” were made to the lighting systems of your van but if all the same “USA” type connectors were used then re-wiring the lighting harnesses will still be a big job but still doable. Having a electrical manual (if available) will really help big time. When you remove the connectors and bulb sockets make sure you do not cut the wiring to close to them and take your time and solder everything together. Don’t be in a hurry. Make sure you use the original stock colors for each of the harness…will make any trouble shooting later a lot easier. MKe sure you wrap each harness separately with high quality vinyl tape.
I doubt very much if you can find someone parting out your year and size of Chevy van but would not hurt to post something in the parts wanted section…..you might get lucky.
Again,welcome aboard and good luck with your project.
